input device

Abstract

To provide an input device having a waterproof structure capable of reliably protecting against water without deforming the cover even if the dimensions of the components are uneven. The input device (1) has a waterproof structure, and the waterproof structure has an operating member (10), which is arranged on the operating part (1a); the cover (20), which is erected around the operating part; An air component (50) whose movement is inputted; and an elastic piece (30) covering the substrate and having an opening (30a) corresponding to the electrical component, and sandwiched between the cover and the substrate. The cover is equipped with The rib (20a) with a substantially convex cross-section abutted by the elastic sheet has a thin-walled part (30c) arranged in the region where the rib abuts. A space is formed on the back side of the thin-walled part, and the thin-walled part is pressed by the rib. And elastic deformation.

Description

technical field [0001] The present invention relates to an input device having a waterproof structure capable of reliably waterproofing without deforming a cover body. Background technique [0002] As an input device used in portable terminal devices and various devices, it is desired to be able to use it safely even in an outdoor environment. For this reason, portable terminal devices and input devices are provided with structures designed to improve waterproofness so that water and the like do not enter the device from the periphery of the operation portion (for example, Patent Document 1). [0003] Figure 8 and Figure 9 It is a sectional view showing the configuration of the portable terminal device 100 described in Patent Document 1. FIG. exist Figure 9 Among them, the waterproof structure of the peripheral portion of the keypad 101 of the portable terminal device 100 includes: an upper cover body 104 having a rib (corresponding to Japanese: リブ) 105 erected around ...

AI Technical Summary

Problems solved by technology

[0008] However, in the conventional structure, when the thickness of the elastic sheet and the height of the ribs are not uniform, the rebound force from the elastic sheet is stronger than expected, and the defect that the upper cover 104 is deformed may occur.

[0009] Therefore, there is a problem that the operation part cannot be operated due to the deformation of the upper cover body 104 or the tactile feeling of the operation is deteriorated.

On the other hand, if the fastening force with the lower case is weakened in order to avoid the above situation, the elastic deformation of the elastic piece cannot sufficiently ensure the adhesive force, and as a result, there is a problem that water enters through the gap.
